Can't use cache_nodes output of aws_elasticache_cluster as a list

[phoolish]

This seems to be the return of #8794

Terraform Version

0.9.6
0.9.2

Affected Resource(s)

Please list the resources as a list, for example:

• aws_elasticache_cluster

Terraform Configuration Files

resource "aws_elasticache_cluster" "memcached" {
  cluster_id = "foo"
  engine = "memcached"

  num_cache_nodes = 3
  node_type = "cache.t2.micro"
}

resource "route_53_record" "memcached-site-com" {
  count = "${length(aws_elasticache_cluster.memcached.cache_nodes)}"
  zone_id = "${aws_route53_zone.site-com.zone_id}"
  name = "${format("node%d.mem.site.com", count.index)}"
  type = "CNAME"
  records = [
    "${element(aws_elasticache_cluster.memcached.cache_nodes.*.address, count.index)}",
  ]
  ttl = "300"
}
